Democrat Jon Ossoff conceded to Republican Karen Handel in the hard-fought race to represent Georgia's 6th District, ending a defiant address to hundreds of disappointed supporters Tuesday with a pledge that the "fight goes on."

Ossoff, a 30-year-old former congressional aide, shattered fundraising records and became a national Democratic rising star with his bid to flip the suburban Atlanta district. But Handel staved off his fierce challenge by consolidating GOP support across the district.

The Democrat said little about his political future – namely whether he would seek to challenge Handel next year – in a brief address to supporters. He has said repeatedly he would have to talk with his fiancée before deciding about another political run.

But his speech suggested he would not stray far from the political spotlight. He thanks his supporters for providing a “beacon of hope for people in Georgia.” And he said his campaign “showed the world that in places where no one thought it was even possible to fight, we could fight.”

“This is not the outcome any of us would hope for,” said Ossoff. “But this is the beginning of something much bigger than us. So thank you – thank you for the most extraordinary experience that I’ve ever had the honor of being a part of.”
